This from an article linked on Instapundit. The paragraphs I find especially interesting:

I would like to say that the answer to our problem is education: teaching kids about the reality of guns as tools for sport and protection, rather than as a means of attracting attention to themselves. I feel such a program would take much of the mystique away from firearms, and allow educators to teach children to handle guns properly, thus cutting down on both youth-related gun crime and accidents.
Such programs have been demonstrated to work, and work well; in a recent report by one of the major television networks, two sets of children were put in a room in which a deactivated handgun was placed. One set of kids was raised by gun owners, who had instructed their children on what (and what not) to do if they ever encountered a gun. The other set of parents were anti-gunners who had taken the “just say no” approach to firearms training. Both parents predicted that their children would leave the gun alone, and seek out an adult for help.
As it turns out, only one of the groups did so. The children who had been properly educated by gun-owning parents refused to touch the gun. They immediately got up and tried to find an adult. They were, in fact, found wandering in the halls, pointing to the room they had left, and warning passing adults about the gun in the room. The other children, who had been brought up on the “just say no” approach, were intoxicated with their exciting, unfamiliar discovery. They immediately began playing with the gun, pointing it at other kids and themselves, pulling the trigger.

Of course, these days, it’s hard enough to find responsible parents.
